Network configuration question

Hi,

Our company is in the process of integrating with some members of another
company. There will be about 10 new users who initially will need to access
resources on their own network and access my network.

Currently my network consists of a single windows 2000 domain with all
clients / servers on the same subnet. I'm looking for some advise as to the
best way to connect the new users to both my network and their own (They are
only moving across the city so a leased line is probably the way to go)

The way I see it (any I hope you will correct me if I'm wrong) is as
follows:

My network remains as is on say 192.168.1.0 subnet. Add one router to
forward traffic from the new users to my network. Place them in a different
subnet e.g 192.168.2.0. Then add one more router and route traffic via
leased line to and from the new users old network through this (e.g. To
subnet 10.0.0.0)

Some questions:
1. How do I configure the clients on both mine and the new user networks.
i.e. currently the default gateway for my clients is the internet firewall.
The new users will probably use their own network resources initially so I
would imagine their default gateway will be the router connecting them to
thier own network. How do I allow communication between me and the new staff
and the new staff and their own network
2. Would there be any point in creating a child domain for the new staff and
creating trusts between each of the networks?


Any advise greatly appreciated

this is routing issue. depends on the router/firewall connecting both sites,
you may need to modify the routing table.

Perfect example of why an "Internet sharing device" (pick your favorite
type/model) should never be the Default Gateway of a system, *except* when
the system only has one subnet and no other router in the system.

........I am assuming everyone will use the same Firewall for the
Internet......
The Default Gateway of the clients will *always* be the router that directly
faces them. If there is more than one router facing them, then it will be
the router representing the path to the most "subnets" and not a router that
leads to a "dead-end".

All routers will have their own Default Gateway set so that the routed
traffic eventually works its way router to router to the one router that
directly faces the Firewall Device. That partcular router then uses the
Firewall Device as its Default Gateway.

Domains have no relationship to subnets. It is apples and oranges, two
differnt things,..no relationship at all. Neither effects the other. I
would probably maintain two distinct Domains (as they probably already are)
and just establish a Trust between them if you need them to interact. But
there is no way I can predict your company's needs with respect to Domain
Security and Domain Interoperability. You will have to study the many
different possibilities and decide that for yourself.
